Apple intelligence different devices with different languages

Hi,

I'm have an iPhone 16 Pro (iOS 26) and a MacBook Pro 2024 (Tahoe 26). My iPhone is in Spanish (México) and my Mac is in English (US).

Every time I turn on Apple Intelligence on my iPhone to use Spanish, my Mac's Apple Intelligence gets updated to use Spanish, and vice versa when I update my Mac's Apple Intelligence to use English, my iPhone automatically updates to use English language.

How can I use Apple Intelligence to use different languages, Spanish on my iPhone and English on my Mac?

Thanks.
